Oscar is correct.
When you calculate discounts & sale price, you do not add them. With sales tax, you only tax what you pay for.
Find the discount price
28.50 • 0.3 = 8.55
Subtract
28.50 - 8.55 = 19.95
Find the sales tax
19.95 • 0.1 = 1.99
Add sales tax
19.95 + 1.99 = 21.94
Oscar paid $21.94
Since Kim wants the same book, she is going to pay the same price.
4x^2-8=136 subtract 136 from both sides
4x^2-144...this is a difference of perfect squares so
(2x+12)(2x-12)
x=±6 or as they put it:
{-6, 6}
The scale factor of the image which is the ratio of the longest side of image and the longest side of the actual rectangle is 0.259
<u>Actual Dimension of rectangle</u> :
- Longest side = 8.5 meters
<u>Scaled dimension of the rectangle</u> :
- Longest side = 2.2 meters
<u>To obtain the scale factor used to produce the image</u> :
- Longest side of image ÷ Longest side of actual triangle
Therefore, the scaled factor used to produce the image of the rectangle is 0.259
